DESCRIPTION¶
The shorewall-lite utility is used to control the Shoreline Firewall Lite (Shorewall Lite).OPTIONS¶
The trace and debug options are used for debugging. See http://www.shorewall.net/starting_and_stopping_shorewall.htm#Trace. The nolock option prevents the command from attempting to acquire the Shorewall-lite lockfile. It is useful if you need to include shorewall commands in /etc/shorewall/started. The options control the amount of output that the command produces. They consist of a sequence of the letters v and q. If the options are omitted, the amount of output is determined by the setting of the VERBOSITY parameter in shorewall.conf[1](5). Each v adds one to the effective verbosity and each q subtracts one from the effective VERBOSITY. Alternately, v may be followed immediately with one of -1,0,1,2 to specify a specify VERBOSITY. There may be no white-space between v and the VERBOSITY. The options may also include the letter t which causes all progress messages to be timestamped.COMMANDS¶
The available commands are listed below. addAdds a list of hosts or subnets to a dynamic zone usually
used with VPN's.
The interface argument names an interface defined in the
shorewall-interfaces[2](5) file. A host-list is comma-separated
list whose elements are host or network addresses.
Caution
The add command is not very robust. If there are errors in the
host-list, you may see a large number of error messages yet a
subsequent shorewall-lite show zones command will indicate that all
hosts were added. If this happens, replace add by delete and run
the same command again. Then enter the correct command.
allow
Re-enables receipt of packets from hosts previously
blacklisted by a drop, logdrop, reject, or
logreject command.
clear
Clear will remove all rules and chains installed by
Shorewall-lite. The firewall is then wide open and unprotected. Existing
connections are untouched. Clear is often used to see if the firewall is
causing connection problems.
If -f is given, the command will be processed by the compiled script that
executed the last successful start, restart or refresh
command if that script exists.
delete
The delete command reverses the effect of an earlier
add command.
The interface argument names an interface defined in the
shorewall-interfaces[2](5) file. A host-list is comma-separated
list whose elements are a host or network address.
disable
Added in Shorewall 4.4.26. Disables the optional provider
associated with the specified interface or provider. Where more
than one provider share a single network interface, a provider name
must be given.
drop
Causes traffic from the listed addresses to be
silently dropped.
dump
Produces a verbose report about the firewall
configuration for the purpose of problem analysis.
The -x option causes actual packet and byte counts to be displayed.
Without that option, these counts are abbreviated. The -m option causes
any MAC addresses included in Shorewall-lite log messages to be displayed.
The -l option causes the rule number for each Netfilter rule to be
displayed.
enable
Added in Shorewall 4.4.26. Enables the optional provider
associated with the specified interface or provider. Where more
than one provider share a single network interface, a provider name
must be given.
forget
Deletes /var/lib/shorewall-lite/filename and
/var/lib/shorewall-lite/save. If no filename is given then the file
specified by RESTOREFILE in shorewall.conf[1](5) is assumed.
help
Displays a syntax summary.
hits
Generates several reports from Shorewall-lite log
messages in the current log file. If the -t option is included, the
reports are restricted to log messages generated today.
ipcalc
Ipcalc displays the network address, broadcast address,
network in CIDR notation and netmask corresponding to the input[s].
iprange
Iprange decomposes the specified range of IP addresses
into the equivalent list of network/host addresses.
iptrace
This is a low-level debugging command that causes
iptables TRACE log records to be created. See iptables(8) for details.
The iptables match expression must be one or more matches that may appear
in both the raw table OUTPUT and raw table PREROUTING chains.
The trace records are written to the kernel's log buffer with facility = kernel
and priority = warning, and they are routed from there by your logging daemon
(syslogd, rsyslog, syslog-ng, ...) -- Shorewall-lite has no control over where
the messages go; consult your logging daemon's documentation.
logdrop
Causes traffic from the listed addresses to be
logged then discarded. Logging occurs at the log level specified by the
BLACKLIST_LOGLEVEL setting in shorewall.conf[1] (5).
logwatch
Monitors the log file specified by the LOGFILE option in
shorewall.conf[1](5) and produces an audible alarm when new
Shorewall-lite messages are logged. The -m option causes the MAC
address of each packet source to be displayed if that information is
available. The refresh-interval specifies the time in seconds between
screen refreshes. You can enter a negative number by preceding the number with
"--" (e.g., shorewall-lite logwatch -- -30). In this case,
when a packet count changes, you will be prompted to hit any key to resume
screen refreshes.
logreject
Causes traffic from the listed addresses to be
logged then rejected. Logging occurs at the log level specified by the
BLACKLIST_LOGLEVEL setting in shorewall.conf[1] (5).
noiptrace
This is a low-level debugging command that cancels a
trace started by a preceding iptrace command.
The iptables match expression must be one given in the iptrace
command being canceled.
reset
All the packet and byte counters in the firewall are
reset.
restart
Restart is similar to shorewall-lite start except
that it assumes that the firewall is already started. Existing connections are
maintained.
The -n option causes Shorewall-lite to avoid updating the routing
table(s).
The -p option causes the connection tracking table to be flushed; the
conntrack utility must be installed to use this option.
restore
Restore Shorewall-lite to a state saved using the
shorewall-lite save command. Existing connections are maintained. The
filename names a restore file in /var/lib/shorewall-lite created using
shorewall-lite save; if no filename is given then Shorewall-lite
will be restored from the file specified by the RESTOREFILE option in
shorewall.conf[1](5).
run
Added in Shorewall 4.6.3. Executes command in the
context of the generated script passing the supplied parameters.
Normally, the command will be a function declared in lib.private.
Before executing the command, the script will detect the configuration,
setting all SW_* variables and will run your init extension script with
$COMMAND = 'run'.
save
The dynamic blacklist is stored in
/var/lib/shorewall-lite/save. The state of the firewall is stored in
/var/lib/shorewall-lite/ filename for use by the shorewall-lite
restore. If filename is not given then the state is saved in the
file specified by the RESTOREFILE option in shorewall.conf[1](5).
show
The show command can have a number of different
arguments:
bl|blacklists
start
Added in Shorewall 4.6.2. Displays the dynamic chain
along with any chains produced by entries in shorewall-blrules(5).The
-x option is passed directly through to iptables and causes actual
packet and byte counts to be displayed. Without this option, those counts are
abbreviated.
capabilities
Displays your kernel/iptables capabilities. The -f
option causes the display to be formatted as a capabilities file for use with
compile -e.
[ [ chain ] chain... ]
The rules in each chain are displayed using the
iptables -L chain -n -v command. If no chain is
given, all of the chains in the filter table are displayed. The -x
option is passed directly through to iptables and causes actual packet and
byte counts to be displayed. Without this option, those counts are
abbreviated. The -t option specifies the Netfilter table to display.
The default is filter.
The -b ('brief') option causes rules which have not been used (i.e. which
have zero packet and byte counts) to be omitted from the output. Chains with
no rules displayed are also omitted from the output.
The -l option causes the rule number for each Netfilter rule to be
displayed.
If the t option and the chain keyword are both omitted and any of
the listed chains do not exist, a usage message is displayed.
classifiers|filters
Displays information about the packet classifiers defined
on the system as a result of traffic shaping configuration.
config
Displays distribution-specific defaults.
connections
Displays the IP connections currently being tracked by
the firewall.
event event
Added in Shorewall 4.5.19. Displays the named
event.
events
Added in Shorewall 4.5.19. Displays all events.
ip
Displays the system's IPv4 configuration.
ipa
Added in Shorewall 4.4.17. Displays the per-IP accounting
counters ( shorewall-accounting[3] (5)).
log
Displays the last 20 Shorewall-lite messages from the log
file specified by the LOGFILE option in shorewall.conf[1](5). The
-m option causes the MAC address of each packet source to be displayed
if that information is available.
marks
Added in Shorewall 4.4.26. Displays the various fields in
packet marks giving the min and max value (in both decimal and hex) and the
applicable mask (in hex).
nat
Displays the Netfilter nat table using the command
iptables -t nat -L -n -v.The -x option is passed directly
through to iptables and causes actual packet and byte counts to be displayed.
Without this option, those counts are abbreviated.
policies
Added in Shorewall 4.4.4. Displays the applicable policy
between each pair of zones. Note that implicit intrazone ACCEPT policies are
not displayed for zones associated with a single network where that network
doesn't specify routeback.
routing
Displays the system's IPv4 routing configuration.
raw
Displays the Netfilter raw table using the command
iptables -t raw -L -n -v.The -x option is passed directly
through to iptables and causes actual packet and byte counts to be displayed.
Without this option, those counts are abbreviated.
tc
Displays information about queuing disciplines, classes
and filters.
zones
Displays the current composition of the Shorewall zones
on the system.
Start Shorewall Lite. Existing connections through
shorewall-lite managed interfaces are untouched. New connections will be
allowed only if they are allowed by the firewall rules or policies.
The -p option causes the connection tracking table to be flushed; the
conntrack utility must be installed to use this option.
stop
Stops the firewall. All existing connections, except
those listed in shorewall-routestopped[4](5) or permitted by the
ADMINISABSENTMINDED option in shorewall.conf[1](5), are taken down. The
only new traffic permitted through the firewall is from systems listed in
shorewall-routestopped[4](5) or by ADMINISABSENTMINDED.
If -f is given, the command will be processed by the compiled script that
executed the last successful start, restart or refresh
command if that script exists.
status
Produces a short report about the state of the
Shorewall-configured firewall.
The -i option was added in Shorewall 4.6.2 and causes the status of each
optional or provider interface to be displayed.
version
Displays Shorewall's version. The -a option is
included for compatibility with earlier Shorewall releases and is
ignored.
EXIT STATUS¶
In general, when a command succeeds, status 0 is returned; when the command fails, a non-zero status is returned. The status command returns exit status as follows: 0 - Firewall is started. 3 - Firewall is stopped or cleared 4 - Unknown state; usually means that the firewall has never been started.FILES¶
